Product Description

GDBC-901 Transformer Turns Ratio Tester TTR Meter with PC Connection

How to perform a power transformer turns ratio test
 

Power transformer turns ratio test is an   an AC low voltage test  which determines the ratio of the high    voltage winding to all other windings at no-load. The turns ratio test is performed on all taps of every winding.

The Transformer Turns Ratio tester (TTR) is a device utilized to determine the ratio of turns between the windings in a transformer. It applies voltage to the leads marked with "H" and measures the resulting voltage on the lead marked with "X" using the testing equipment.

The ratio measurements are performed on all tap positions, and the ratio is calculated by dividing the measured induced voltage by the applied voltage. In the case of three-phase transformers, the ratio is measured individually on each phase using a three-phase TTR, and the process is repeated until ratio measurements for all three phases are completed.

Introduction

• The voltage ratio measurement for three or singe phase transformer 

• The group vector measurement for three phase transformer.

• The polarity measurement for single phase transformer or CT/PT

• Voltage ratio error calculation

• Current transformer ratio measurement

• Excitation current measurement in ratio testing

• Reproduction the AC test voltage from power source to reduce the effects of bad power source

• Save the test results in the memory internal the tester

• Print the test results by micro printer

• Reverse connection detect unit to prevent the high voltage injected to operator

• Over current protection unit integrated in software and hardware

• Upload the test results to PC by RS232 and make word report by software
